Three target solar vacuum tube
Three target Solar Evacuated Tube: high thermal efficiency, more durable for low temperature and high temperature. Its membrane target at bottom is typically made of copper. Absorption layer and antireflective layer is compound of Nitrogen and aluminum, adding some component of stainless steel. Comparing to the general tubes, it maintains more efficient in heat preservation. Meanwhile, the chemical compound in the absorption target is more pure than normal solar vacuum tube, thus possessing the more efficient absorption rate.

Raw materials
The material is 3.3 high borosilicate glass
it is a kind of special type glass material with the features of low expansion coefficient,high temperature resistance,high intensity, high rigidity, transparency and chemical stability. It doesn't explode in high temperature, and can be forged and drawn to variety of formation when soften.
All these splendid features enable it to be widely used in the field of solar energy,chemical industry, pharmaceutical packaging, electric light source,artificial crystal, artificial craft decoration and so on.Compared with ordinary glass. It's non poisonous, and it has made the big progress in its mechanical property, thermal stability, hydrolytic resistance.acid resistance and alkali resistance glass
